> Hi all,
> 
> Proposal:
>     Put DiffArray in its own diffarray package
>     http://hackage.haskell.org/trac/ghc/ticket/3370
> 
> DiffArray currently has serious performance problems; see
>     http://hackage.haskell.org/trac/ghc/ticket/2727
> and is not currently being actively maintained. However, as part of the
> corelib array it gives the impression that it is a "blessed" library.
> 
> I propose that we split DiffArray off into its own diffarray package.
> This also has the advantage that it can then be maintained by a separate
> maintainer, if someone is interested, and it will be decoupled from
> GHC's major release schedule.
> 
> Deadline: 26 July (2 weeks).
